net: phylink: add mac_managed_pm in phylink_config structure

2022-10-15T10:51:51Z

The recent commit 'commit 744d23c71af3 ("net: phy: Warn about incorrect mdio_bus_phy_resume() state")' requires the MAC driver explicitly tell the phy driver who is managing the PM, otherwise you will see warning during resume stage. Add a boolean property in the phylink_config structure so that the MAC driver can use it to tell the PHY driver if it wants to manage the PM.

net: phylink: Adjust advertisement based on rate matching

2022-09-23T10:55:36Z

This adds support for adjusting the advertisement for pause-based rate matching. This may result in a lossy link, since the final link settings are not adjusted. Asymmetric pause support is necessary. It would be possible for a MAC supporting only symmetric pause to use pause-based rate adaptation, but only if pause reception was enabled as well.

net: phylink: Adjust link settings based on rate matching

2022-09-23T10:55:35Z

If the phy is configured to use pause-based rate matching, ensure that the link is full duplex with pause frame reception enabled. As suggested, if pause-based rate matching is enabled by the phy, then pause reception is unconditionally enabled. The interface duplex is determined based on the rate matching type. When rate matching is enabled, so is the speed. We assume the maximum interface speed is used. This is only relevant for MLO_AN_PHY. For MLO_AN_INBAND, the MAC/PCS's view of the interface speed will be used. Although there are no RATE_ADAPT_CRS phys in-tree, it has been added for comparison (and the implementation is quite simple).

net: phylink: Generate caps and convert to linkmodes separately

2022-09-23T10:55:35Z

If we call phylink_caps_to_linkmodes directly from phylink_get_linkmodes, it is difficult to re-use this functionality in MAC drivers. This is because MAC drivers must then work with an ethtool linkmode bitmap, instead of with mac capabilities. Instead, let the caller of phylink_get_linkmodes do the conversion. To reflect this change, rename the function to phylink_get_capabilities. Signed-off-by: Sean Anderson Signed-off-by: David S. Miller

net: phylink: Export phylink_caps_to_linkmodes

2022-09-23T10:55:35Z

This function is convenient for MAC drivers. They can use it to add or remove particular link modes based on capabilities (such as if half duplex is not supported for a particular interface mode). Signed-off-by: Sean Anderson Signed-off-by: David S. Miller

net: phylink: Document MAC_(A)SYM_PAUSE

2022-09-23T10:55:35Z

This documents the possible MLO_PAUSE_* settings which can result from different combinations of MAC_(A)SYM_PAUSE. Special note is paid to settings which can result from user configuration (MLO_PAUSE_AN). The autonegotiation results are more-or-less a direct consequence of IEEE 802.3 Table 28B-2.

net: phylink: remove phylink_helper_basex_speed()

2022-04-13T11:38:44Z

As there are now no users of phylink_helper_basex_speed(), we can remove this obsolete functionality. Signed-off-by: Russell King (Oracle) Signed-off-by: David S. Miller

net: phylink: remove phylink_set_pcs()

2022-02-28T11:57:49Z

As all users of phylink_set_pcs() have now been updated to use the mac_select_pcs() method, it can be removed from the phylink kernel API and its functionality moved into phylink_major_config(). Removing phylink_set_pcs() gives us a single approach for attaching a PCS within phylink. Signed-off-by: Russell King (Oracle) Signed-off-by: David S. Miller
